SAWMILL APPLIANCE.

Application filed April 13, 1907.

Specification of Letters Patent.

Patented April 18, 1909.

Serial No. 368,982.

To all whom it may concern:

Be it known that I, JAMES R. HODGEN, a citizen of the United States, residing at Tensaw, in the county of Baldwin and State of Alabama, have invented a new and useful Sawmill Appliance, of which the following is a specification.

The invention relates to a saw mill appliance.

The object of the present invention is to improve the construction of saw mills, and to provide simple and inexpensive means for increasing the capacity and for practically doubling the out-putof saw mills, by enabling lumber to be cut during the backward or return movement of a saw mill carriage.

A further object of the invention is to provide an appliance of this character, adapted to be readily applied to any ordinary saw mill, and capable of maintaining the saw mill carriage and the material firm and steady, during the backward or return movement, and adapted to prevent the carriage and the material from being lifted or turned over by the saw, which, during the return or backward movement of the carriage, strikes thev material from underneath the same.

Another object of the invention is to enable the log to be readily released, when it is necessary to turn the same.

\Vith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :Figure 1 is an end elevation partly in section, showing a saw mill appliance constructed in accordance with this invention, and applied to a saw husk and a saw mill carriage. Fig. 2 is a longitudinal sectional view, taken substantially on the line wm of Fig. 1. Fig. 3 is a plan view of a portion of the saw mill husk and the saw mill carriage, illustrating the arrangement of the top rail. Fig. 4c is a detail perspective view of the top clamping block or member, and the means for operating the $211116.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a reciprocatory sawmill carriage, which may be of any preferred con struction and which operates to carry a log 2 to a circular saw 3. The circular saw 3 is mounted on a shaft or mandrel 4, which is journaled in suitable bearings of a saw husk 5 and which may be operated in any suitable manner.

The saw mill carriage, which is equipped in the usual manner, is reciprocatable past the saw in both directions and is mounted on wheels 6 and 7, arranged to run on rails 8 and 9. The wheels 6 adjacent to the saw are grooved in the usual manner, and the bottom rail 8 is provided with a projecting rib or flange to fit the grooves 10 of the wheels 6.

In order to hold the saw mill carriage firm and steady during the backward or return movement of the same, when the saw strikes the log from underneaththe latter, the saw husk is provided with a top rail 11, which fits in the grooves 10 of the wheels 6 at the tops thereof, and which elfectually prevents the saw from lifting or over-turning the saw mill carriage. The top rail, which preferably consists of a rod of metal, arranged edgewise, may be of any preferred construction, and it is designed to be connected with the saw husk 5 by suitable transverse arms 12, secured to the saw husk in any preferred manner.

The log is held firmly on the saw mill carriage by means of a transversely disposed top block or clamping member 13, which prevents the material from being lifted or over-turned by the saw, when the latter strikes the leg from underneath the same during the backward or return movement of the carriage. Any number of top blocks or members 13 may be employed, and each block or member, which extends across the saw mill carriage, is pivotally mounted at its rear end, or the end located at the side opposite that at which the saw is arranged. The rear end of the top block or member is supported by links or bars let and 15, arranged in pairs and located at the side faces of the block or member. The links or bars 14 are arranged substantially vertical, and the other links or bars 15 are inclined, and the upper terminals of both pairs of bars or members are secured to the. top. block or member. by bolts, or other suitable fastening devices, and their lower endsv are pivoted to. the carriage by a suitable bolt or pin 16, which pierces the ends of the said bars or links I l and 15,

and which pass through upwardly extending;

ears. 1'? of a bracket or plate 18. The front end of the top block or member engages the log at the upper face thereof, as clearly illustrated in Fig. 1 of the accompanying drawings.

The top. block or member is operatedi to raise and lower it. from the: log-by means of a lever 19, consisting of a long arm or bar, extending. upward from the top. block or member and. pivoted by a pin or bolt 20' to the same at the. upperface thereof and: provided at its pivoted end. with a; short arm. 21, arranged substantially at right angles tothe bar or body portion of the operating lever 19L The short arm 21 isconnected with the saw mill carriage by means of a rod 22,. piv- QtBd! at its lower end; 23 to: the frame of the earriage,.and similarly connected at itsv upper end 24-t0 the outer-end of the short arm 21. By this arrangement, the top. block or mem her will be raised or-lowered when the operating; lever is; oscillated.

The operating lever is guided in its oscih latory movement by a. pairof spaced arcuaate ratchet bars or members 25,. secured at their terminals to the upper face of the top block or member, which is provided at an intermediate point with. a longitudinal slot 26'. The rod 22: and the short arm of the Lever are adapted to operate in: the longitudinal slot of the top; block or member, and the lever is: locked at any adjustment by means of a pivoted: dog on detent 2T, whiclr is connected with. suitable operating mechanism. The operating mechanisnr for raising and lowering the top block. or member and. the ratchet mechanism, is adapted to. hold: the said top block; or member in engagement with the log, which may be readily released, when: it: is necessary to turn the saane.v

It will be seen that the improvements-here in shown and described are adapted to be readily applied to any saw mill,.and that the capacity of the same will be materially increased and the output practically doubled.

Having thus fully described; my invention, what I claim as new and. desire to secure by Letters Patent, is

1.. The combination; with a saw husk, a circular saw, and a; track, of a. saw mill carriage having supporting wheels: and reciprocatabl'e past the saw in both directions, a clampingmember arranged to extend over and engage the top of the material for clamp, ing the-same upon the saw mill carriage, and a: fixed top rail located above and arranged to engage the carriage supporting wheels nearer the saw to prevent the saw mill earriage from being lifted by the saw. while cutting on the back or return movement of the carriage.

2. The combination with a saw, and a saw mill carriage, of a top block or member extending across the saw m1ll carriage and arranged to engage the upper face of the ma- .terial for preventing the same from being lifted while cutting on the backward or return movement of the carriage, and means connected with the carriage and mounted on and carried by the topblock or member for operating the latter;v

3.- The combination with a saw, and a saw mill carriage, of transversely disposedtop block or member extending across the saw mill carriage and pivota lly mounted'at its rear end and having its front end arranged to engage the material at the upper face thereof, an operating lever mounted on and carried. by the top block or member, means for connecting the top block or member with the sawmill: carriage, and means for locking the lever in its adjustment.
